"Nanowalker" the Bipedal DNA Robot

New Scientist has an article about a DNA
bipedal robot that has been created and is taking its first
steps. This microscopic robot called "NanoWalker" is just 10
nanometers long and it's made
from DNA fragments! Researchers at New York State University say
their robot is the first nanoscale bipedal robot to succeed. The
robot walks along a kind of DNA track and is able to detach its legs
and reattach them further down. The robot is so tiny the researchers
couldn't even see the robot actually walk, they had to do experiments
to see if the DNA fingerprint they expected from the walk had been
created. The researchers hope for their next feat to make the walker
carry a load!
